I'm totally new here. I'd like to know what are the modules if removed will be not risky on the board to boot up to the OS, the point from this is inserting custom modules (Like Ozmosis bootloader).Also all of my use will be only based on UEFI bootloaders and OSes.

@Dongos:Welcome at Win-RAID Forum!MethylatorX's question has not been answered here, because we haven't yet found anybody, who was willing to remove all original BIOS modules one after the other and sent us thereafter a report about what happened in each case. Even if we ever should get such report, the results are not transferable to all other mainboards.There are modules, which can be removed without any problem, but the removal of another module may make your system completely unusable. That is why this should generally not be done by newbees.
